Adjusting the Fuser
The Fuser uses heat and pressure to bond the toner image to the paper. For optimal print quality, the
printer automatically adjusts the temperature of the Fuser when you change the paper type. Because
of differences in paper construction and thickness, the adjustment made by the printer is not enough
or is too much for all paper types. If the Fuser temperature is too low, the toner will not properly bond
to the paper. If the Fuser is too hot, the paper can curl.
Changing the Fuser temperature for a particular paper type requires entering Service Mode and editing
NVM using a specific Chain-Link code. Refer to “NVM Read and Write (Edit NVM)” on page 2-28 for
detailed instructions on editing NVM values.
To adjust the Fuser:
1. Identify the paper type for which you need to adjust the fuser temperature.
2. Enter Service Mode and navigate to Printer Diag > Engine Diag > NVM Settings > Edit NVM.
3. Enter the Chain-Link code for the paper identified in step 1. Refer to the table for the appropriate
Chain-Link code.
4. Adjust the value up or down as necessary, using one of the following settings:
-9, -6, -3, 0 (default), +3, +6, +9.
The value of the setting raises (if positive) or lowers (if negative) the Fuser temperature by that
many degrees celsius above or below the default temperature for the specified paper type and
printer speed. For example, entering +3 will raise the temperature by 3° C.
